INTRODUCTION

1
A solid or semisolid lubricant consisting of a thickening agent (soap or other additives) in a
fluid lubricant (usually petroleum lubricating oil) is called grease.
Grease is a lubricant which has been thickened in order that it remains in contact with moving
surfaces and not leak out under gravity or centrifugal action.
ASTM defines lubricating grease as “A solid to semi-solid product consisting of dispersion of a
thickening agent in a liquid lubricant.”
There has been a need since ancient times for lubricating greases. The Egyptians used mutton
fat and beef tallow to reduce axle friction in chariots as far back as 1400 B.C. Good lubricating
greases were not available until the development of petroleum based oils in the late 1800’s.
Today there are many different types of lubricating greases but the basic structure of these
greases is similar.
Greases are used where a mechanism can only be lubricated infrequently and where a
lubricating oil would not stay in position. In general greases contain 70-95% of base oils, 5-
20% of thickening agent, and 0-10% of additives.
Depending on type of thickening agents different types of greases are classified as follows.
Calcium
Lithium
Titanium
Sodium
Aluminium
Clay
Polyurea and others
There are two different methods by which grease can be manufactured.
Batch process
Continuous process
The manufacture of lubricating greases has shown constant progress with time. This holds true
for raw materials, equipments, processes, and formulations.

2
RAW MATERIAL
As this definition indicates, there are three components that form lubricating grease. These
components are oil, thickener and additives. The base oil and additive package are the major
3
components in grease formulations, and as such, exert considerable influence on the behavior
of the grease. The thickener is often referred to as a sponge that holds the lubricant (base oil
and additives).
BASE OIL
Most greases produced today use mineral oil as their fluid components. These mineral oil-
based greases typically provide satisfactory performance in most industrial applications. In
extreme temperature conditions (low or high), grease that utilizes synthetic base oil provide
better stability.
When formulating grease the selection of base fluid is not only about product properties, it’s
also about production costs. And a significant proportion of the production cost is the amount
of soap required to achieve a certain NLGI grade. The solvating power of the base fluid affects
the amount of soap needed. The following test was performed to determine the difference in
amounts of soap needed between naphthenic (high solvating power) and paraffinic (lower
solvating power) oils.
NLGI grade 2 greases were produced using three naphthenic oils with increasing degrees of
refining and a paraffinic oil, all of approximately the same viscosity. As can be seen, the
naphthenic oils with higher solvating power result in a saving of as much as 25% on soap
consumption if you compare the oil with the lowest aniline point with the paraffinic oil. This
would obviously have a significant impact on production costs as 25% less soap would be
needed to produce the same NLGI grade.
Another production cost to consider is energy consumption. When “cooking” the grease, the
temperature must be raised until the fatty acids are dissolved. Obviously the higher the
temperature needed, the more energy is consumed. Higher temperatures also increase the risk
of soap oxidation.
The difference in the solution temperature of hydroxystearic acid in three naphthenic oils
with different degrees of refining and one paraffinic oil. The concentration of hydroxystearic
acid in each oil was 30 wt%, which is representative of the typical concentration during grease
cooking. As can be seen, the temperature at which the fatty acid dissolves is significantly lower
for all the naphthenic oils than for the paraffinic oil. The lower temperatures needed in greases
with naphthenic oils is due to their higher solvating power.
Oils with higher solvating power by definition have a higher capability of dissolving
additives. The additives are dissolved at lower temperatures and smaller amounts of them are
4
required to achieve the same grades.
Effect of base oil on grease properties
Due to the higher solvating power of naphthenic oils they display a higher affinity
towards the soap. In naphthenic-based greases there is a prevalence of physiochemical
interaction between the oil and the soap, as opposed to paraffinic-based greases where most of
the oil is physically rather than physiochemically trapped in the soap structure. This means the
naphthenic oil is more intimately bonded with the soap structure and displays a lower tendency
to separate or bleed from the grease.

THICKENER
The thickener is a material that, in combination with the selected lubricant, will produce the
solid to semi fluid structure. The primary type of thickener used in current grease is metallic
soap. These soaps include lithium, aluminum, clay, Polyurea, sodium and calcium. Lately,
complex thickener-type greases are gaining popularity. They are being selected because of
their high dropping points and excellent load-carrying abilities.
Complex greases are made by combining the conventional metallic soap with a complexing
agent. The most widely used complex grease is lithium based. These are made with a
combination of conventional lithium soap and a low- molecular-weight organic acid as the
complexing agent. Non-soap thickeners are also gaining popularity in special applications such
as high-temperature environments. Smectonite or Bentonite and silica aerogel are examples of
thickeners that do not melt at high temperatures. There is a misconception, however, that even
though the thickener may be able to withstand the high temperatures, the base oil will oxidize
quickly at elevated temperatures, thus requiring a frequent relube interval.
ADDITIVES
Additives can play several roles in lubricating grease. These primarily include enhancing the
existing desirable properties, suppressing the existing undesirable properties, and imparting
new properties. The most common additives are oxidation and rust inhibitors, extreme
pressure, antiwear, and friction-reducing agents. In addition to these additives, boundary
lubricants such as molybdenum disulfide or graphite may be suspended in the grease to reduce
friction and wear without adverse chemical reactions to the metal surfaces during heavy
loading and slow speeds

TYPE OF GREASES
SOAP BASED GREASE
Soap based grease contains organic or inorganic thickeners. It is formed when the fatty acid or
ester (from either animals or vegetables) is mixed with an alkali (such as lithium) and then
heated under pressure with agitation. The process of this chemical reaction, which takes place
is known as saponification.
LITHIUM GREASE.
7
(1) Lithium grease is smooth, buttery-textured and by far the most popular when compared to
all others. The normal grease contains lithium 12-hydroxystearate soap. It has a dropping point
around 205°C and can be used at temperatures up to about 150°C It can also be used at
temperatures as low as (-)35°C. It has good shear stability and a relatively low coefficient of
friction, which permits higher machine operating speeds. It has good water-resistance, but not
as good as that of calcium or aluminum base. Pumpability and resistance to oil separation are
good to excellent. It does not naturally inhibit rust, but additives can provide rust resistance.
Anti-oxidants and extreme pressure additives are also responsive in lithium greases.
(2) Lithium complex grease and lithium soap grease have similar properties except the
complex grease has superior thermal stability as indicated by a dropping point of 260°C. It is
generally considered to be the nearest thing to true multipurpose grease.
CALCIUM GREASE.

(1) Calcium or lime grease, the first of the modern production greases, is prepared by reacting
mineral oil with fats, fatty acids, small amount of water, and calcium hydroxide (also known as
hydrated lime). The water modifies the soap structure to absorb mineral oil. Because of water
evaporation, calcium grease is sensitive to elevated temperatures. It dehydrates at temperatures
around 79°C at which its structure collapses, resulting in softening and, eventually, phase
separation. Greases with soft consistencies can dehydrate at lower temperatures while greases
with firm consistencies can lubricate satisfactorily to temperatures around 93°C. In spite of the
temperature limitations, lime grease does not emulsify in water and is excellent at resisting
“wash out.” Also, its manufacturing cost is relatively low. If calcium grease is prepared from
12-hydroxystearic acid, the result is an anhydrous (waterless) grease. Since dehydration is not a
concern, anhydrous calcium grease can be used continuously to a maximum temperature of
around 110°C

(2) Calcium complex grease is prepared by adding the salt calcium acetate. The salt provides
the grease with extreme pressure characteristics without using an additive. Dropping points
greater than 260°C can be obtained and the maximum usable temperature increases to
approximately 177 °C. With the exception of poor pumpability in high-pressure centralized
systems, where caking and hardening sometimes occur calcium complex greases have good all-
around characteristics that make them desirable multipurpose greases.
SODIUM GREASE.
Sodium grease was developed for use at higher operating temperatures than the early hydrated
calcium greases. Sodium grease can be used at temperatures up to 121°C but it is soluble in
water and readily washes out. Sodium is sometimes mixed with other metal soaps, especially
calcium, to improve water resistance. Although it has better adhesive properties than calcium
grease, the use of sodium grease is declining due to its lack of versatility. It cannot compete
with water-resistant, more heat-resistant multipurpose greases. It is, however, still
recommended for certain heavy-duty applications and well-sealed electric motors.
8
ALUMINUM GREASE.
(1) Aluminum grease is normally clear and has a somewhat stringy texture, more so when
produced from high-viscosity oils. When heated above 79°C this stringiness increases and
produces a rubber like substance that pulls away from metal surfaces, reducing lubrication and
increasing power consumption. Aluminum grease has good water resistance, good adhesive
properties, and inhibits rust without additives, but it tends to be short-lived. It has excellent
inherent oxidation stability but relatively poor shear stability and pumpability.
(2) Aluminum complex grease has a maximum usable temperature of almost 100 °C higher
than aluminum-soap greases. It has good water-and-chemical resistance but tends to have
shorter life in high-temperature, high-speed applications.
NON-SOAP BASED GREASE
A non-soap based grease consists of inorganic like molybednum disulphide and graphite, as
well as organic thickeners. The organic thickeners are considered as non-abrasives, which have
high capacity to absorb and "hold" the base oil.

POLYUREA GREASE.
9
Polyurea is the most important organic non soap thickener. It is a low-molecular-weight
organic polymer produced by reacting amines (an ammonia derivative) with iso cyanates,
which results in an oil soluble chemical thickener. Polyurea grease has outstanding resistance
to oxidation because it contains no metal soaps (which tend to invite oxidation). It effectively
lubricates over a wide temperature range of -20 to 177 °C and has long life. Water-resistance is
good to excellent, depending on the grade. It works well with many elastomer seal materials. It
is used with all types of bearings but has been particularly effective in ball bearings. Its
durability makes it well suited for sealed-for-life bearing applications
.
ORGANO-CLAY.
Organo-clay is the most commonly used inorganic thickener. Its thickener is modified clay,
insoluble in oil in its normal form, but through complex chemical processes, converts to
platelets that attract and hold oil. Organo-clay thickener structures are amorphous and gel-like
rather than the fibrous, crystalline structures of soap thickeners. This grease has excellent heat-
resistance since clay does not melt. Maximum operating temperature is limited by the
evaporation temperature of its mineral oil, which is around 177 °C. However, with frequent
grease changes, this multipurpose grease can operate for short periods at temperatures up to its
dropping point, which is about 260 °C. A disadvantage is that greases made with higher-
viscosity oils for high thermal stability will have poor low temperature performance. Organo-
clay grease has excellent water-resistance but requires additives for oxidation and rust
resistance. Work stability is fair to good. Pumpability and resistance to oil separation are good
for this buttery textured grease.

CHARACTERISTICS
12
As with oil, grease displays its own set of characteristics that must be considered when being
chosen for an application. The characteristics commonly found on product data sheets include
the following:
PUMPABILITY
Pumpability is the ability of a grease to be pumped or pushed through a system. More
practically, pumpability is the ease with which pressurized grease can flow through lines,
nozzles and fittings of grease-dispensing systems.

WATER RESISTANCE
This is the ability of grease to withstand the effects of water with no change in its ability to
lubricate. Soap/water lather may suspend the oil in the grease, forming an emulsion that can
wash away or, to a lesser extent, reduce lubricity by diluting and changing grease consistency
and texture.

CONSISTENCY
Grease consistency depends on the type and amount of thickener used and the viscosity of its
base oil. Grease’s consistency is its resistance to deformation by an applied force. The measure
of consistency is called penetration. Penetration depends on whether the consistency has been
altered by handling or working. ASTM D 217 and D 1403 methods measure penetration of
unworked and worked greases. To measure penetration, a cone of given weight is allowed to
sink into a grease for five seconds at a standard temperature of 25°C. The depth, in tenths of a
millimeter, to which the cone sinks into the grease, is the penetration. A penetration of 100
would represent solid grease while a penetration of 450 would be semi fluid.

DROPPING POINT
Dropping point is an indicator of the heat resistance of grease. As grease temperature increases,
penetration increases until the grease liquefies and the desired consistency is lost. The dropping
point is the temp which grease becomes fluid enough to drip. The dropping point indicates the
upper temperature limit at which grease retains its structure, not the max temperature at which
grease may be used.

OXIDATION STABILITY
This is the ability of grease to resist a chemical union with oxygen. The reaction of grease with
oxygen produces insoluble gum, sludge and lacquer-like deposits that cause sluggish operation,
increased wear and reduction of clearances. Prolonged exposure to high temperatures
accelerates oxidation in greases.

13
HIGH-TEMPERATURE EFFECTS
High temperatures harm greases more than they harm oils. Grease, by its nature, cannot
dissipate heat by convection like circulating oil. Consequently, without the ability to transfer
away heat, excessive temperatures result in accelerated oxidation or even carbonization where
grease hardens or forms a crust. Effective grease lubrication depends on the grease's
consistency. High temperatures induce softening and bleeding, causing grease to flow away
from needed areas. The mineral oil in grease can flash, burn or evaporate at temperatures
greater than 177°C
LOW-TEMPERATURE EFFECTS
If the temperature of grease is lowered enough, it will become so viscous that it can be
classified as hard grease. Pumpability suffers and machinery operation may become impossible
due to torque limitations and power requirements. As a guideline, the base oil's pour point is
considered the low-temperature limit of grease.

TYPICAL FLOWCHART FOR BATCH PROCESS
Batch production is the most common manufacturing method. The steps of manufacturing
include the following.
1. Bulk ingredients are metered or weighed into the processing reactor. For soap-based
greases made by saponification (the process of forming soap by splitting a fat with an
alkali), the fatty ingredient, alkali and a portion of the oil are added to the reactor. By
19
Filling
heating (300 - 450°F) and mixing, the fat is converted to soap, and the soap is dispersed
throughout the mixture. This may be done in open kettles or in closed pressure kettles.
After completion of saponification and dehydration (removal of water), the remaining
oil is added to the batch to lower the temperature. Next, the grease is milled or
homogenized.
2. This step of homogenization or milling is very important, because it will produce a
uniform crystal and gel structure that will not change when the grease is used.
Homogenizing the grease will break down the solid particles or fibers and will disperse
the resultant small particles in the liquid. It also breaks up lumps, eliminates graininess
and produces a smooth product. Homogenization of certain types of greases will stiffen
the grease producing lower penetration value. Homogenization can improve texture and
“brighten” grease’s appearance. In many cases this homogenization process is carried
out at temperatures greater than 200°F (93°C).
3. After homogenization, the grease is further cooled, desecrated and packaged. Of course,
it is understood that there are many different grease manufacturing methods depending
on the type of grease and the manufacturer.

MATERIAL OF

MATERIAL OF CONSTRUCTION
Carbon Steel for Reactor
Structural Steel for vessel supports
Carbon steel, also called plain carbon steel , is a metal alloy , a combination of two elements ,
iron and carbon, where other elements are presents in quantities too small to affect the
properties. The only other allowing element allowed in plain-carbon steel are manganese
(1.65% max), silicon (0.60% max), and copper (0.60% max). Steel with low carbon content has
the same properties as iron, soft but easily formed. As carbon content rises, the material
becomes harder and stronger but less ductile but difficult to weld. Higher carbon contents
lowers steel’s melting point and its temperature resistance in general.

Carbon content influences the yield strength of steel because carbon molecules fit into the
interstitial crystal lattice sites of body centered cubic arrangement of the iron molecules. The
interstitial carbon reduces the mobility of dislocations, which in turn has a hardening effect on
iron. To get dislocations to move, a high enough stress level must be applied in order for
dislocations to “break away”. This is because the industrial carbon atoms cause some of the
iron BCC lattice cells to distort.
Typical compositions of carbon:

• Mild (low carbon) steel: Approximately 0.05-0.15% carbon content for low carbon
steel and 0.16-0.29% carbon content for mild steel (e.g. AISI 1018 steel). Mild steel has
a relatively low tensile strength, but it is cheap and malleable; surface hardness can be
increased through carburizing.
• Medium carbon steel: Approximately 0.30-0.59% carbon content (e.g. AISI 1040
steel). Balances ductility and strength and has good wear resistance; used for large
parts, forging and automotive components.
• High carbon steel: Approximately 0.6-0.99% carbon content. Very strong, used for
spring and high- strength wires.
39
• Ultra-high carbon steel: Approximately 1.0-2.0% carbon content. Steel that can be
great hardness. Used for special purposes like (non-industrial purpose) knives, axles or
punches. Most steel with more than 1.2% carbon content are made using powder
metallurgy and usually fall in the category of high alloy carbon steel.
Steel can be heat-treated which allows parts to be fabricated in an easily-formable soft state. If
enough carbon is present, the alloy can be hardened to increase strength, wear, and impact
resistance. Steel are often wrought by cold-working methods, which is the shaping of metal
through deformation at a low equilibrium or metastable temperature.
METALLURGY
Carbon steel which can successfully undergo heat-treatment have carbon content in the range
of 0.30-1.70% by weight. Trace impurities of various other elements can have a significant
effect on the quality of the resulting steel. Trace amounts of sulfur in particular make the
redlow alloy carbon steel, such as A36 grade , contains about 0.05% sulfur and melts around
1426-1538 C (2600-2800F). manganese is often added to improve the harden ability of low
carbon steels. These addition turn the material into low alloy steel by some definition , but
AISI’s definition of carbon steel allows up to 1.65% manganese by weight.
40
Structural steel for vessel support
Structural steel is steel construction material, a profile, formed with a specific shape or cross
section and certain standards of chemical composition and strength . Structure steel shape, size,
composition, strength, storage etc., is most industrialized countries.
Structural steel , such as I-beams, has a large polar moment of inertia, which allows the beam
to be very stiff in respect to its cross- section area.
Structural steel in construction: - A primed steel beam is holding up the floor above, which
consists of a metal deck (Q-Deck), upon which a concrete slab has been poured.
Most industrialized countries prescribe a rage of standard steel grades with different strength,
corrosion resistance and other properties.
Thermal properties
The properties of steel vary widely, depending on its alloying elements. The austenizing
temperature, the temperature where steel transform to an austenite structure, for steel at 900°C
for pure iron, then, as more carbon is added, the temperature falls to a minimum 724°C for
steel (steel with only 0.83% by weight of carbon in it). As 2.1% carbon (by mass) is
approached, the austenizing temperature climbs back up, to 1130°C. Similarly, the melting
point of steel changes based on the alloy.
The lowest temperature at which plain carbon steel can begin to melt, its solids, is 1130°C.
Steel never turns into a liquid below this temperature. Pure iron (‘steel’ with 0% carbon) starts
to melt at 1492°C, and is completely liquid upon reaching 1539°C. Steel with 2.1% Carbon by
weight begins melting at 1130°C and is completely molten upon reaching 1315°C. ‘Steel’ with
more than 2.1% Carbon is no longer steel, but is known as cast iron.
41
REACTOR DESIGN

57
Utility services are supplied from a central site facility, and include:
1. Electricity
2. Steam
3. Cooling water
4. Water for general use
5. Effluent disposal facilities
6. Air
7. Chilled water

1. ELECTRICITY
The power required for the processes, compressors, motor drives, lighting and general
use may be generated on site, but more usually will be purchased from the local
company. The voltage at which the supply is taken or generated will depend on the
demand.
2. COOLING WATER
Natural and forced - draft cooling towers are generally used to provide the cooling
water required on a site unless water can be drawn from a convenient river or lake in
sufficient quantity. Cooling water is needed for cooling of reactor after reaction.
3. WATER
The water required for general purposes on a site will usually be taken from the local
mains supply, unless cheaper source of suitable quality water is available from a river,
lake or well.
4. EFFLUENT DISPOSAL
58
Facilities will be required at all sites for the disposal of waste minerals without creating
a public nuisance. The disposal of aqueous waste and toxic waste to public sewers and
surface waters is controlled by legislation. Strict controls are placed on the nature of
effluent that can be discharged.
I grease manufacturing as such no effluents will form. But remaining grease is recycle
back or either incineration methods are used.

5. CHILLED WATER
The chilled water, which absorbed heat from the air, is sent via return lines back to the utility
facility, where the process described in the previous section occurs. Utility generated chilled
water eliminates the need for chillers and cooling towers at the property, reduces capital
outlays and eliminates ongoing maintenance costs.
The advantage of utility-supplied chilled water is based on economy of scale. A utility can
operate one large system more economically than a customer can operate the individual system
in one building. The utility's system also has back-up capacity to protect against sudden
outages. The cost of such "insurance" is also markedly lower than what it would be for an
individual structure.
The use of utility supplied chilled water is most cost effective when it is designed into the
building’s infrastructure or when chiller/cooling tower equipment must be replaced.
Commercial customers often lower their air conditioning costs from 10-20% by purchasing
chilled water.
6. STEAM
In other industrial applications steam is used for energy storage, which is introduced and
extracted by heat transfer, usually through pipes. Steam is a capacious reservoir for energy
because of water's high heat of vaporization.
59
SITE SELECTION
60
Plant location plays critical role in the economic viability of the process. Hence it is
desirable to select a plant place with safer working condition, cheap and skilled labor,
availability of raw material and probable effect of waste generated.
Profitability factors:
1. Raw Material
For this plant raw materials are
• Base oil
• 12-hydroxy stearic acid
• Lithium hydroxide
• Additives
All of the raw materials should be made available near the plant location. Base oil
receiving from HPC refinery while additives supply receive from various chemical companies
like Lubrizol. Transportation and handling are the major contributor to the cost of these raw
materials. Thus it is advantageous to set a plant near a location were these raw materials are
available.
2.Environmental Factors:
61
Now-a-days environmental factor has become most important for site location. Since this
project does not create any hazardous waste, environmental factor is not critical for this project.
Productivity factors:
1.Energy consideration:
Process requires continuous supply of electricity to fulfill consumers necessities. Also the
availability of Fuel is important. To enhance productivity continuous supply of energy is
essential.
2.Labour
Hostile labor can affect continuous profile of the plant. If the labor is a militant one it
creates adverse effects on the project. Hence to maintain the productivity labour factor should
be reconsider. Skilled and friendly labor is available in Mumbai. Similarly they are available in
cheaper rate.
3.Storage
Timely delivery of raw materials should be ensured to minimize inventory.
4.Transporatation:
Transport of raw material and product is important. For this particular project, the required raw
materials are transported by trucks. Site should have well connectivity by rail, road.
5.Availability of utilities:
62
Utilities required for the production facility must be easily available
Other Factors:
1. Government Policies and Public Opinion
If the state government policies are not in favor of setting up of new project, it may take time to
get the required clearances and finally it will result in delaying of the project and project cost
goes up. Since byproduct in manufacturing of grease is only the water, which will not affect the
environment. So there will not be any problem for getting license from the government
regarding the environmental issues.

FACTORS AFFECT ON GROWTH OF GREASE
MANUFACTURING INDUSTRIES
1. Second World War
The Second World War, particularly for aircraft lubricating grease was a large factor in the
progress of grease manufacture and the development of new types of lubricating greases.
2. Industrial Growth.
Basic industries to which improved lubricating greases have made a valuable contribution
are steel manufacture industries. Lubricating grease has played a steadily increasing role in
maintaining maximum capacity of the various operating units that make up a steel plant.
3. Growth in Automotive Sector.
The lubricating grease industry can also take pride in the fact that it made valuable and
important contribution to the operation of equipment used in vehicles, which are used for
transportation of goods and people.

WORLDWIDE GREASE USE
Central and Eastern Europe account for the majority of worldwide grease usage, Fig. followed
by Asia-Pacific, North America, Western Europe, Central and South America, Africa and the
Middle East. A significant difference in the types of products used exists among these regions.
Western Europe and North America typically require higher quality products than do Central
and Eastern European users. Africa uses specialized products (such as greases for mining
equipment) and the use of Polyurea products predominates in Asia.
Throughout the world, industrial applications account for most of the grease used for railroad,
general manufacturing, steel production and mining predominate Among automotive
applications, trucks and buses account for the majority of grease used, followed by
agricultural/construction equipment and passenger cars
75

WORLDWIDE PRODUCTION OF GREASE
According to the 2007 NLGI Grease Survey, North America reported grease production of 544
million pounds, which is approximately 29 percent of the worldwide grease production. All
countries participating in the 2007 survey reported a total production of 1.9 billion pounds of
grease.

North America reports a higher percentage of aluminum complex, calcium sulfonate, lithium
complex, Polyurea and clay greases in comparison to the international data. Conversely, the
worldwide production reports higher percentages of hydrated calcium, conventional lithium
and sodium soap grease. This could be due to a difference in equipment lubrication demands in
various parts of the world. In general, high-speed or heavily loaded equipment can generate
more heat, which creates an increased need for greases with higher dropping points. In
addition, higher labor costs in North America factor into the need to extend relubrication
intervals and therefore increase the need for grease that can function for longer periods of time.
76
PRODUCTION OF GREASE IN INDIA
According to the 2007 NLGI Grease survey, India reported grease production of 344 million
pounds, which is approximately 12 percent of the worldwide grease production. All countries
participating in the 2007 survey reported a total production of 1.9 billion pounds of grease.
India reports a higher percentage of lithium, lithium complex and greases in comparison to the
international data. This could be due to a difference in equipment lubrication demands in
various parts of the India. In general, high-speed or heavily loaded equipment can generate
more heat. Which creates an increased need for grease with higher dropping points. In addition,
higher labor costs in India factor into the need to extend relubrication intervals and therefore
increase the need for grease that can function for longer periods of time.

77
TYPE OF GREASE USE IN WORLDWIDE
Conventional lithium is the most popular grease type in all regions, but leads lithium complex
only by one percent in North America. Polyurea production accounted for a higher production
percentage in Japan than in other regions. Hydrated calcium grease accounted for the second
highest production in China, the Pacific region and in the Caribbean region.

The Process units and ancillary buildings should be laid to give the most economical flow of
materials and personnel around the site. Hazardous processes must be located at a safe distance
from the buildings. Consideration must also be given to future expansion of plant. The
ancillary buildings and services required are storage, maintenance, workshops, stores for
maintenance, laboratories for quality control, fire station, utilities, offices for general
administration, canteens and car parks.
When roughing the preliminary site layout the process units will normally be sited first
and arranged to give a smooth flow of materials through the various processing steps from raw
materials to final product. Storage process units are normally placed at least 30m apart.
Adopting a layout that gives the shortest run of connecting pipe between equipment,
and the least amount of structural work can minimize the cost of construction.
CONSIDERATIONS IN LAYOUT:
1. OPERATION :
Equipments that need to have frequent operator attention like the two reactors should be
near to the control room. Equipments that require frequent dismantling such as compressors
and large pumps should be placed under cover.
2. PLANT EXPANSION:
Equipment should be located so that it can be conveniently tied up with any future
expansion of the process.
3. ADMINISTRATIVE OFFICES:
They should be close to the main entrances so as to facilitate movement of personnel working
there. Canteen should be close to security offices, management service buildings, time office.
4. TANK FARMS & UTILITIES:
They should be close to the roads connecting main roads.

TESTING OF GREASES
• Cone Penetration
• Dropping Point
• Mechanical Stability
• Rolling stability
• Oxidation Stability
• Anti Wear
• Extreme Pressure
• Water Washout
• Oil Separation
• Evaporation Loss
• Corrosion
• Rust

86
KEY TEST: - CONE PENETRATION.
Aim:- The penetration is determined at 25 °C by releasing the cone assembly
from penetrometer and allowing the cone to the drop freely in the grease
for 5 seconds.
Two type of penetration
 Worked penetration
 Unworked penetration

87
WORKED PENETRATION:-
It is the penetration of grease sample subjected to 60 double strokes in standard grease
worker and penetration done at 25°C.
UNWORKED PENETRATION:-
It is the penetration at 25°C of grease, which is transferred in grease worker cup and
leveled with minimum working.
PROCEDURE FOR WORKED PENETRATION:-
Fill the cup with grease. Jar the cup from time to time to remove any air entrapped. Fill
excess grease above rim. Assemble the worker with vent open. Plunger pull out and close the
cap slightly and place the plunger bottom. Close the vent, bring the cup and tighter cup remove
excess grease to 60 full double strokes of the plunger to top open the vent, remove the plunger
along with the top of the cup level the grease and determine the penetration as described in
upward penetration.
PROCEDURE FOR UNWORKED PENETRATION:-
 Place 400gm to 500gm test sample in a fridge to 25+/-2c. Transfer the grease preferably in
lumps to the cup. Jar the cup to remove the entrapped air. Scrape off the excess grease
extending above the rim by moving the blade of spetula (knife) held inclined towards the
direction of motion at an angle 45c across the rim of cup.
 Clean the penetrometer cone thoroughly before each test.( Rotation of cone to be avoided).
 Place the cup on the table of the penetrometer. Set the mechanism to hold cone in the 0
position and adjust apparatus carefully so that the tip of the cone just touches the surface of
the test sample. Release the cone shaft rapidly, and allow to drop for 5 seconds freely. Read
the penetrometer reading to read penetration reading gently depressed the indicator shaft
until the dial touché the cone shaft.
 For sample having penetration lesser than 200 use the sample for doing additional
penetration by allowing the cone to drop at some other place near the previous and not
allowing to the side.
88
The depth, in tenths of a millimeter, to which the cone sinks into the grease is the penetration.
A penetration of 100 would represent a solid grease while one of 450 would be semi-fluid. The
NLGI has established consistency numbers or grade numbers, ranging from 000 to 6,
corresponding to specifies ranges of penetration numbers.
The following table lists the NLGI grease classification along with a description of the
consistency of each classification.
NLGI GREASE CLASSIFICATION:-
NLGI grade Penetration at 25 deg C Consistency
000 445-475 Semi-fluid
00 400-430 Semi-fluid
0 355-385 Very soft
1 310-340 Soft
2 265-295 Common grease
3 220-250 Semi hard
4 175-205 Hard
5 130-160 Very hard
6 85-115 Solid
TEST METHOD FOR WORKING STABILITY OF GREASE IN PRESENCE
OF WATER .
Aim:- The method is intended for the determination of change when subjected to work in
presence of water.
Working:- Grease is filled in cup and exposed to prolonged mechanical working in presence of
water (10% water) and in absence of water and difference in penetration is determined.
DROPPING POINT TEST:-
89
Aim:- This method covers the determination of dropping point of lubrication grease. This point
being the temperature at which first drop of material falls from cup.
Working:- Small quantity of grease is taken in drop point and heated slowly to the temperature
at which first drop of the oil comes out from the hole bottom of the test cup. The temperature at
which grease drop falls is noted as the dropping point of the grease.
DETERMINATION OF HEAT STABILITY TEST:-
Aim:- The method describes a procedure for the determination of heat stability of grease by
observing the separated out and structure of the grease after test.
Working:- About 10 gm. Grease is heated at 120 °C for 1hr and grease is examine visually for
any evidence of oil separation and structure change after 24hrs.
DETERMINATION OF EVAPORATION LOSS TEST:-
Aim:- This method covers determination of the evaporation loss in lubricating grease.
Working:- The sample weighted in Petri dish and kept for 2hrs. in oven maintained at 105+/-
10°C. The loss in mass is calculated as evaporation loss of sample.
OXIDATION STABILITY TEST:-
Aim:- The method for oxidation stability of lubricating grease bomb method.
Working:- The sample of grease is oxidized in bomb heated to 99°C and fitted with oxygen at
7.5 bar. Pressure is observed and recorded at started. Then the degree of oxidation after a given
period of time determined by corresponding decrease in oxygen pressure.
ROLL STABILITY TEST:-
